A method and device are disclosed for treating ulcers based on the photobiostimulation effect to reduce inflammation and enhance microvascular activity accelerating the wound healing process. In a preferred embodiment, a diode laser source emits 1470±60 nm laser energy at about 15 Watts, which is conveyed through an optical fiber and applied onto wound with about a 7 mm spot with a laser pulse preferably set to about 60 msec. An enclosure cap at emission tip confining irradiated area results in enhanced personnel safety. A standalone handheld laser can be used without need of a fiber/handpiece. Additionally a timer or sensing system determines end of radiation treatment. An efficient, rapid, easy and safe treatment of venous, arterial and neurotrophic ulcers, chronic and acute, results. In another embodiment, a special technique is used with a point to point laser appliance, irradiating an area of about 1-2 cm out beyond the edges of the ulcers. After each treatment, a hyaluronic acid gel is generally applied. Optimum treatment can involve multiple irradiations spaced over days/weeks. |
